Council Member Guest Editorial E-newsletter: No 107. October 2010 Deadline for next issue: Wednesday 14 November 2012 Council member guest editorial In 2005, I remember giving a presentation to my fellow reference librarians at Christchurch City Libraries on a range of electronic resources providing information about New Zealand’s environment. The Network’s website particularly impressed me and it wasn’t long before I signed up as a member. Back then, I never would have predicted that I would have the opportunity to contribute to that impressive website, but here I am doing just that! As many of you will have read in the August issue of Trilepidea, the Network’s website is undergoing some redevelopment to improve usability. I am enjoying the challenge of helping to improve access to the amazing trove of information contained on our website. I’ve rediscovered hidden corners of the website I’d forgotten about and great new additions such as the lichens and macroalgae species pages. The amazing range of images contributed by hundreds of photographers is a powerful resource that will feature more prominently in the redeveloped site. The new site will be launched soon and I am looking forward to hearing what people think about the changes. Keep your ears and eyes open for the new website and please send your feedback to: [email protected]. There will also be some exciting changes to the Favourite Native Plant vote this year. Though some people may find this annual exercise a bit frivolous, I think it provides a good excuse to share our love for native plants with everyone. For many Network members, obscure plants are dear to their hearts. When these less-well known species rank highly in the Favourite Native Plant voting, it draws attention to diversity of our native flora. It is interesting to see how the voting patterns have changed over the years the Network has run the vote. In the early days, the obvious iconic species dominated but, within a short time, these have been replaced by rare, unusual or threatened species. Last year both the Favourite Native Plant and the Bird of the Year winners were wetland species (giant bamboo rush Sporadanthus ferrugineus and pukeko, respectively). These results contrast with the negative associations wetlands have in popular culture. Wetlands are rich in diversity and, with so few original wetlands remaining, I find it heartening to see wetland species gaining some ‘celebrity status’. Last year I felt a bit like a celebrity handler travelling from Wellington to Invercargill with a floweringAstelia solandri. The Air New Zealand flight staff were very considerate in allowing me to bring my precious plant as additional carry-on luggage. On the flight, I had several people ask me about my plant and I shamelessly used it as an excuse to talk about native plants and encourage people to visit our website and cast their vote. Many people were impressed at the beauty of the flower and surprised to hear it was a native. I encourage you all to vote again this year and please ask your fiends, families and work colleagues to log on and vote too. What publicity stunt will you pull for an excuse to talk to a stranger about native plants?

Olearia cheesemanii forms a large shrub or small tree that can grow up to 4 m tall. It is endemic to both North and South Islands; from Ohinemuri River in Waikato to the Tararua Ranges in the North Island but in the South Island it is confined to North West Nelson and the Westport area. In the spring and early summer, it becomes covered in white daisy flowers that make it a very attractive shrub for the garden. Its bark is grey, flaking in long strips with the smaller branchlets covered in a buff tomentum. It can be propagated easily from semi- hardwood cuttings or fresh seed and grows best in moist soils in sun or semi-shade. Olearia cheesemanii is most likely to be confused with the O. arborescens. It differs in its narrower, lanceolate leaves, usually smaller stature, and its habitat preferences. The Network fact sheet for Olearia cheesemanii may be found at: Olearia cheesemanii.

This work includes the 18 metre tall Chatham Island grass tree (tarahinau)—Dracophyllum arboreum—and the pineapple tree (mountain neinei)—Dracophyllum traversii. This Dracophyllum work is based on the PhD of Fanie Venter (Venter 2009). There are still two species for which we still seek images. They are Dracophyllum pearsonii and D. politum.

New Zealand bluebells (Wahlenbergia) Jessie Prebble ([email protected]) The mostly southern-hemisphere genus Wahlenbergia (common names bluebells or harebells) comprises 260 species in the family Campanulaceae. It is one of the largest genera in the family, second only to the mostly northern-hemisphere genus Campanula. The centre of diversity of Wahlenbergia is South Africa, where about 170 species occur (or 65% of the genus). Australia and New Zealand form a secondary centre of diversity, with 29 species currently recognised in Australia, and 10 species in New Zealand. The New Zealand species of Wahlenbergia were last revised by Judith Petterson (Petterson 1997a), who started working on the genus for her MSc thesis in 1953. Sadly, Judith passed away in 2007. Recently, I studied the phylogenetics and species delimitation of Wahlenbergia focusing on New Zealand for my Wahlenbergia pygmaea (or should MSc thesis at Victoria University (Prebble 2010). That work is that be W. albomarginata?) from the Kaweka Ranges. Photos: Jesse Prebble. summarised below. In collaboration with Chris Cupido from Cape Town, and with my supervisors Heidi Meudt and Phil Garnock-Jones, I constructed the first phylogeny of Wahlenbergia, using the chloroplast trnL-F marker and the nuclear ribosomal ITS marker (Prebble et al., 2011). By using a molecular clock, we determined that the genus evolved in South Africa about 30 million years ago (mya), then dispersed to Australia about 5 mya. The New Zealand species form two clades, both rooted within the Australasian clade. This led us to suggest there have been two dispersal events to New Zealand, one leading to a radiation of species with a rhizomatous herbaceous growth form 1.6 mya, and the other leading to a radiation of species with the radicate (also known as tufted) growth form, 0.7 mya. We then explored the relationships and current taxonomy of the New Zealand and Australian species of Wahlenbergia by sequencing many more individuals, and using an additional chloroplast marker, trnK-psbA (Prebble et al., 2012a). The phylogeny was poorly resolved due to low levels of genetic variation in all three markers and some conflict between the nuclear and chloroplast markers. With increased sampling, the pattern of the two introductions from Australia to New Zealand was not so clear. It still appears most likely that the New Zealand rhizomatous species are 3 the result of a single introduction from Australia, but no New Zealand radicate clade was recovered. Due to the general lack of resolution, I also tested the use of AFLP markers on a small dataset and found they could well prove a useful technique for delimiting the New Zealand species of Wahlenbergia (Prebble et al., 2012b). Combining and integrating all available data on Wahlenbergia, including results from the DNA sequencing studies (Prebble et al., 2011; 2012a), the AFLP study (Prebble et al., 2012b), Judith’s morphological work (Petterson 1997a), information on chromosome counts (Petterson et al., 1995), and habitat information (Petterson 1997a), has several implications for the current taxonomy (Prebble et al., 2012b).

T Issued February, 1930 PLANT MATERIAL INTRODUCED BY THE OFFICE OF FOREIGN PLANT INTRODUCTION, BUREAU OF PLANT INDUSTRY, JULY 1 TO SEPTEMBER 30,1928 (NOS. 77261 TO 77595) CONTENTS Page Introductory statement 1 Inventory 3 Index of common and scientific names 19 INTRODUCTORY STATEMENT The most outstanding plant material contained in this inventory, No. 96, covering the period from July 1 to September 30, 1928, is the collection of 51 sugarcane varieties (Saccarum offvoinarum, Nos. 77334 to 77384) procured by E. W. Brandes in New Guinea for use in his official investigations. Part of the interest in this shipment is due to the fact that Doctor Brandes is the first agricultural explorer to use an airplane for his collecting tour. Doctor Brandes not only collected sugarcanes in person but also obtained the cooper- ation of P. H. Goldfinch, Sydney, Australia, who sent in a collection of 44 varieties (Nos. 77496 to 77539). Another lot of five varieties (Nos. 77298 to 77302) was received from Argentina. As in the previous inventory, the bulk of the plant material received in this period comes from the Southern Hemisphere. Through the activities of Mrs. Frieda Cobb Blanchard two collections of Australian plants (Nos. 77273 to 77292 and Nos. 77441 to 77447), as well as a collection from New Zealand (Nos. 77540 to 77582), were received. Through O. F. Cook there was received a collection of rubber-producing plants (Nos. 77387 to 77394) from Haiti. Five kinds of cover crops (Nos. 77293 to 77297) from Ceylon may be of value for the southern United States.

Abstract Patterns of flammability across the vascular plant phylogeny, with special emphasis on the genus Dracophyllum by Xinglei Cui Fire has been part of the environment for the entire history of terrestrial plants and is a common disturbance agent in many ecosystems across the world. Fire has a significant role in influencing the structure, pattern and function of many ecosystems. Plant flammability, which is the ability of a plant to burn and sustain a flame, is an important driver of fire in terrestrial ecosystems and thus has a fundamental role in ecosystem dynamics and species evolution. However, the factors that have influenced the evolution of flammability remain unclear.

  • The Island Rule and Its Application to Multiple Plant Traits
    The island rule and its application to multiple plant traits Annemieke Lona Hedi Hendriks A thesis submitted to the Victoria University of Wellington in partial fulfilment of the requirements for the degree of Master of Science in Ecology and Biodiversity Victoria University of Wellington, New Zealand 2019 ii “The larger the island of knowledge, the longer the shoreline of wonder” Ralph W. Sockman. iii iv General Abstract Aim The Island Rule refers to a continuum of body size changes where large mainland species evolve to become smaller and small species evolve to become larger on islands. Previous work focuses almost solely on animals, with virtually no previous tests of its predictions on plants. I tested for (1) reduced floral size diversity on islands, a logical corollary of the island rule and (2) evidence of the Island Rule in plant stature, leaf size and petiole length. Location Small islands surrounding New Zealand; Antipodes, Auckland, Bounty, Campbell, Chatham, Kermadec, Lord Howe, Macquarie, Norfolk, Snares, Stewart and the Three Kings. Methods I compared the morphology of 65 island endemics and their closest ‘mainland’ relative. Species pairs were identified. Differences between archipelagos located at various latitudes were also assessed. Results Floral sizes were reduced on islands relative to the ‘mainland’, consistent with predictions of the Island Rule. Plant stature, leaf size and petiole length conformed to the Island Rule, with smaller plants increasing in size, and larger plants decreasing in size. Main conclusions Results indicate that the conceptual umbrella of the Island Rule can be expanded to plants, accelerating understanding of how plant traits evolve on isolated islands.

  • Flowering Records of Some Subalpine Trees and Shrubs
    PETER HAASE 19 Department of Plant and Microbial Sciences, University of Canterbury, Private Bag, Christchurch, New Zealand Present address: Dyckerhoffstrasse 3, 4540 Lengerich, Federal Republic of Germany. FLOWERING RECORDS OF SOME SUBALPINE TREES AND SHRUBS AT ARTHUR'S PASS, NEW ZEALAND Summary: The flowering periodicity and intensity of some subalpine trees and shrubs at Pegleg Flat, Arthur's Pass National Park, was recorded from 1981/82 to 1984/85. Moderate to heavy flowering of most species in 1981/82 was followed by two years of little or no flowering in 1982/83 and 1983/84; almost all species observed flowered heavily in 1984/85. No clear correlation was found between flowering intensity and mean summer temperatures of the previous growing season, when flower buds were initiated. It is suggested that the extent of flower bud initiation may also depend on current carbohydrate and mineral nutrient levels in the plants, which are temporarily depleted after mass-flowering years. The observed 3-year cycle of heavy flowering coincides with previous records for many other New Zealand trees and shrubs. Keywords: Flowering records, periodic flowering, climatic control, summer temperature, subalpine scrub. Introduction Methods Periodic flowering, i.e., the tendency to flower Pegleg Flat, situated near the summit of Arthur's Pass moderately to heavily in some years, but only lightly (42°54' S, 171°34' E), is a small river flat at an or not at all in others, has been described for a altitude of 830 m a.s.l. which was created by the number of New Zealand forest trees, e.g., Nothofagus deposition of a young river terrace of the Otira River.

  • Interactive Effects of Climate Change and Species Composition on Alpine Biodiversity and Ecosystem Dynamics
    Interactive effects of climate change and plant invasion on alpine biodiversity and ecosystem dynamics Justyna Giejsztowt M.Sc., 2013 University of Poitiers, France; Christian-Albrechts University, Germany B. Sc., 2010 University of Canterbury, New Zealand A thesis submitted to Victoria University of Wellington in partial fulfilment of the requirements for the degree of Doctor of Philosophy School of Biological Sciences Victoria University of Wellington Te Herenga Waka 2019 i ii This thesis was conducted under the supervision of Dr Julie R. Deslippe (primary supervisor) Victoria University of Wellington Wellington, New Zealand And Dr Aimée T. Classen (secondary supervisor) University of Vermont Burlington, United States of America iii iv “May your mountains rise into and above the clouds.” -Edward Abbey v vi Abstract Drivers of global change have direct impacts on the structure of communities and functioning of ecosystems, and interactions between drivers may buffer or exacerbate these direct effects. Interactions among drivers can lead to complex non-linear outcomes for ecosystems, communities and species, but are infrequently quantified. Through a combination of experimental, observational and modelling approaches, I address critical gaps in our understanding of the interactive effects of climate change and plant invasion, using Tongariro National Park (TNP; New Zealand) as a model. TNP is an alpine ecosystem of cultural significance which hosts a unique flora with high rates of endemism. TNP is invaded by the perennial shrub Calluna vulgaris (L.) Hull. My objectives were to: 1) determine whether species- specific phenological shifts have the potential to alter the reproductive capacity of native plants in landscapes affected by invasion; 2) determine whether the effect of invasion intensity on the Species Area Relationship (SAR) of native alpine plant species is influenced by environmental stress; 3) develop a novel modelling framework that would account for density-dependent competitive interactions between native species and C.

  • Origin, Diversification, and Classification of the Australasian Genus Dracophyllum (Richeeae, Ericaceae)
    ORIGIN, DIVERSIFICATION, AND Steven J. Wagstaff,2 Murray I. Dawson,2 CLASSIFICATION OF THE Stephanus Venter,3 Je´roˆme Munzinger,4 Darren M. Crayn,5 Dorothy A. Steane,6 and AUSTRALASIAN GENUS Kristina L. Lemson7 DRACOPHYLLUM (RICHEEAE, ERICACEAE)1 ABSTRACT The genus Dracophyllum Labill. (Ericaceae) has a fragmented distribution in Australasia, but reaches the greatest level of species richness and morphological diversity in New Zealand. We investigated evolutionary processes that contribute to this disparity in species richness by comparing DNA sequences from members of Dracophyllum, its close relatives Richea Labill. and Sphenotoma R. Br. ex Sweet (together constituting tribe Richeeae Crayn & Quinn), along with more distant relatives in the Ericaceae. We created complementary data sets for the chloroplast-encoded genes matK and rbcL. Parsimony, Bayesian, and maximum likelihood analyses were conducted to assess the robustness of our phylogenetic inferences. The results were largely congruent and, when analyzed in combination, provided greater resolution. In our analyses, tribe Richeeae formed a monophyletic group that diverged during the Eocene (at least 33.3 million years ago [Ma]) with a crown radiation during the Early Miocene (at least 16.5 Ma) that resulted in two disjunct lineages. This date corresponds roughly to the onset of aridification in central Australia. The southern Western Australian genus Sphenotoma formed an isolated evolutionary lineage, while Dracophyllum and Richea together formed a second lineage restricted to eastern Australia, Lord Howe Island, New Caledonia, and New Zealand. The relationships of the Tasmanian endemic, D. milliganii Hook. f., remain an enigma. It was ambiguously placed as sister to Sphenotoma or to the Dracophyllum–Richea clade.
